Abstract

A disc player capable of playing discs of different types such as: discs where only a digital audio signal is contained in a first frequency band;
discs where only an analog audio signal is contained in a frequency band other than the first frequency band; and, discs where digital and audio signals are contained in the first frequency band and the other frequency band. Processing arrangements are further included to determine (according to disc size and/or presence of a table of contents) whether a currently loaded disc is recorded in the same format as a previous disc which was loaded immediately prior thereto, and if the same, playing the currently loaded disc according to the same reproduction settings as those for the previous disc.
